What two numbers multiply to 711 and add up to 88?

Here we answer the question: "What two numbers multiply to 711 and add up to 88?"

The answer to your question is:

9 and 79

Below we illustrate and prove that 9 and 79 multiply to 711 and add up to 88:

9 × 79 = 711
9 + 79 = 88

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x² + 88x + 711 = 0

If so, the solution to factor the quadratic equation above is:

(x + 9 ) (x + 79)

To summarize, since 9 and 79 multiply to 711 and add up 88, you know that the following is true:

x² + 88x + 711 = (x + 9 ) (x + 79)
